Detailed Description

Macro Definition Documentation

◆ SIP_REFERRED_BY_INIT

#define SIP_REFERRED_BY_INIT ( )

Initializer for structure sip_referred_by_t.

A static sip_referred_by_t structure for Referred-By header must be initialized with the SIP_REFERRED_BY_INIT() macro. For instance,

#define SIP_REFERRED_BY_INIT()
Initializer for structure sip_referred_by_t.
Definition sip_protos.h:11572
#define sip_referred_by(sip)
Access a SIP Referred-By header structure sip_referred_by_t from sip_t.
Definition sip_protos.h:11555
Structure for Referred-By header.
Definition sip.h:604

◆ SIPTAG_REFERRED_BY

#define SIPTAG_REFERRED_BY (   x)

Tag list item for pointer to a Referred-By header structure sip_referred_by_t.

The SIPTAG_REFERRED_BY() macro is used to include a tag item with a pointer to a sip_referred_by_t structure in a tag list.

Parameters
xpointer to a sip_referred_by_t structure, or NULL.

The corresponding tag taking reference parameter is SIPTAG_REFERRED_BY_REF().

◆ SIPTAG_REFERRED_BY_STR

#define SIPTAG_REFERRED_BY_STR (   s)

Tag list item for string with Referred-By header value.

The SIPTAG_REFERRED_BY_STR() macro is used to include a tag item with a string containing value of a sip_referred_by_t header in a tag list.

Parameters
spointer to a string containing Referred-By header value, or NULL.

The string in SIPTAG_REFERRED_BY_STR() can be converted to a sip_referred_by_t header structure by giving the string s has second argument to function sip_referred_by_make().

The corresponding tag taking reference parameter is SIPTAG_REFERRED_BY_STR_REF().

Function Documentation

◆ sip_is_referred_by()

int sip_is_referred_by ( sip_header_t const *  header)
inline

Test if header object is instance of sip_referred_by_t.

Check if the header class is an instance of Referred-By header object and return true (nonzero), otherwise return false (zero).

Parameters
headerpointer to the header structure to be tested
Return values
1(true) if the header is an instance of header referred_by
0(false) otherwise

◆ sip_referred_by_copy()

sip_referred_by_t * sip_referred_by_copy ( su_home_t home,
sip_referred_by_t const *  hdr 
)
inline

Copy a list of Referred-By header header structures sip_referred_by_t.

The function sip_referred_by_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the list of header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be copied

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old hdr header, including the encoding of the old header, if present.

Example
referred_by = sip_referred_by_copy(home, sip->sip_referred_by);
sip_referred_by_t * sip_referred_by_copy(su_home_t *home, sip_referred_by_t const *hdr))
Copy a list of Referred-By header header structures sip_referred_by_t.
Definition sip_protos.h:11702
Returns
A pointer to newly copied header structure, or NULL upon an error.

◆ sip_referred_by_dup()

sip_referred_by_t * sip_referred_by_dup ( su_home_t home,
sip_referred_by_t const *  hdr 
)
inline

Duplicate a list of Referred-By header header structures sip_referred_by_t.

Duplicate a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
referred_by = sip_referred_by_dup(home, sip->sip_referred_by);
sip_referred_by_t * sip_referred_by_dup(su_home_t *home, sip_referred_by_t const *hdr))
Duplicate a list of Referred-By header header structures sip_referred_by_t.
Definition sip_protos.h:11659
Returns
A pointer to the newly duplicated sip_referred_by_t header structure, or NULL upon an error.

◆ sip_referred_by_format()

sip_referred_by_t * sip_referred_by_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Referred-By header from formatting result.

Make a new sip_referred_by_t object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and parses the formatting result to the structure sip_referred_by_t.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Returns
A pointer to newly makes header structure, or NULL upon an error.

◆ sip_referred_by_init()

sip_referred_by_t * sip_referred_by_init ( sip_referred_by_t  x[1])
inline

Initialize a structure sip_referred_by_t.

An sip_referred_by_t structure for Referred-By header can be initialized with the sip_referred_by_init() function/macro. For instance,

sip_referred_by_t * sip_referred_by_init(sip_referred_by_t x[1])
Initialize a structure sip_referred_by_t.
Definition sip_protos.h:11590

◆ sip_referred_by_make()

sip_referred_by_t * sip_referred_by_make ( su_home_t home,
char const *  s 
)
inline

Make a Referred-By header structure sip_referred_by_t.

The function sip_referred_by_make() makes a new sip_referred_by_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Returns
A pointer to newly maked sip_referred_by_t header structure, or NULL upon an error.

Variable Documentation

◆ sip_referred_by_class

msg_hclass_t sip_referred_by_class[]
extern

Header class for Referred-By header.

The header class sip_referred_by_class defines how a SIP Referred-By header is parsed and printed. It also contains methods used by SIP parser and other functions to manipulate the sip_referred_by_t header structure.
